There is no need to re-calibrate the detectors after installation. The equipment is designed to be fully operational after all wiring is completed. For more technical and wiring information please refer to the Automatic Exhaust Fan Controllers For Parking Garages & Carbon Monoxide Transducers data sheets. LOCATION Please refer to the attached data sheet titled “Carbon Monoxide System Layouts in Parking Garages” SS102H & SS102HC-1 GENERAL INFORMATION The SS102H is partially housed in a plastic case, which mounts on and becomes the cover of, a standard 4SD electrical box (provided by the installer). The SS102HC-1 is housed in a plastic case that is attached to a 4x4 plaster ring. It mounts on any four inch square electrical box. A low voltage, four conductor, #18 (or larger) cable connects each SS102H, or SS102HC-1 sensor to the SS103 control panel. There must be an individual cable between each sensor and its control panel group of four terminals. These terminals are labeled on the sensor cover adjacent to the terminal strip. Set up color coding so that the cable will match the same terminals at the sensor and control panel. The SS102HC-1 has four pigtail leads: two red for power and a white and black for output. There is an internal switch in the SS102HC-1 located on the printed circuit board that must be set to volts. SS102H SENSOR OPERATION The SS102H sensors have two lights: one green and one red. The green light is a pilot light showing the unit is on and operational. When power is first applied to the unit, the green light will be off for 1 1/2 minutes while the sensor goes through a warm-up cycle. After this 1 1/2 minute delay, the green light will be on continuously. The red light, which is normally off, is part of a supervisory circuit that monitors critical functions of the unit. A failure in the sensor is shown by a lighted red light, and at the same time a full range (about 4.8 volts) output on terminal A, to actuate relays in the control panel. The SS102H was factory calibrated, and cannot be re-calibrated on site. A functional test can be performed by holding a lit cigarette (a good source of carbon monoxide) under the SS102H, so smoke drifts up through the sensor. This will cause the SS102H to produce an output voltage to actuate the SS103 control panel. If the installation is in a parking garage, a gasoline powered vehicle can be operated near the sensor to provide a system test. See the Carbon Monoxide Transducers data sheet for more technical information. Although the SS102H is usable within a few minutes of being turned on, it will not reach its calibrated level for about 1 week. The SS102H must be continuously powered. 1 MACURCO CONTROLLERS & DETECTORS (CONT.) SS102HC-1 SENSOR OPERATION The SS102HC-1 is a microcomputer controlled sensor. It has a 2 1/2 minute warm up cycle, during which its outputs progressively increase from 1.0 to 2.1 volts. The internal switch must be set to volts. The green LED type light turns on and off during the 2 1/2 minute warm up cycle. At the end of the warm up cycle, the light switches to a steady on, to indicate normal operation. See the Carbon Monoxide Transducers data sheet for more technical information. The SS102HC-1 is supervised. Various critical operating parameters are measured and any problems are indicated by the green light turning off and the output going to a high voltage (about 2.9v), to cause the control panel to actuate the exhaust fan. STABILIZATION TIME Although the units will be fully operational within a few minutes of being first powered, the SS102H gas sensor requires up to 7 days to reach its final operating point and the SS102HC-1 up to 3 days. The unit is intended to be continuously powered. SENSOR POISONS The gas sensing tip in the detector is designed with extreme sensitivity to the environment. As a result, the sensing function of the tip may be deteriorated if it is exposed to a direct spray from a...
